摘要

工程地质条件包括岩土性质、地质构造、地貌、水文地质条件、不利地质作用等。其中，断层、裂隙、褶皱、岩溶、岩性变化等严重影响山地隧道、水工隧道等工程的安全和造价。为此，提出了一种基于特征融合的伦敦和谢菲尔德地质异常检测新方法。建立了面向城市地下空间属性信息建模和可视化的三维栅格数据模型，获取地质数据。在此基础上，采用基于多属性地质异常体的特征级融合提取方法，对地下空间地质数据的多属性数据进行提取、融合、填充和表面处理。平滑处理可以实现地下空间异常地质体的探测。实践证明，该方法可用于地质数据显示、特征提取、特征融合和异常物理检测。

A detection method of urban underground geological anomalies in the United Kingdom based on feature fusion

Engineering geological conditions include the nature of rock and soil, geological structure, landform, hydrogeological conditions, and adverse geological processes. Among them, faults, fissures, folds, karst, and lithology changes seriously affect the safety and construction cost of mountain tunnels, hydraulic tunnels, and other projects. For this reason, a new method based on feature fusion is proposed to detect the geological anomalies in London and Sheffield. It established a 3D raster data model oriented to attribute information modeling and visualization of urban underground space to obtain geological data. Based on this acquired data, authors adopted the feature-level fusion extraction method based on the multi-attribute geological abnormal body to extract, fuse, fill and surface the multi-attribute data of underground space geological data. Smooth processing can realize the detection of abnormal geological bodies in underground space. It has been proved that this method can be used in geological data display, feature extraction, feature fusion, and abnormal physical examination.
